Integer built-in type.
</brief_description>
<description>
Signed 64-bit integer type.
It can take values in the interval [code][-2^63, 2^63 - 1][/code], i.e. [code][-9223372036854775808, 9223372036854775807][/code]. Exceeding those bounds will wrap around.
[int] is a [Variant] type, and will thus be used when assigning an integer value to a [Variant]. It can also be enforced with the [code]: int[/code] type hint.
[codeblock]
var my_variant = 0 # int, value 0
my_variant += 4.2 # float, value 4.2
var my_int: int = 1 # int, value 1
my_int = 4.2 # int, value 4, the right value is implicitly cast to int
my_int = int("6.7") # int, value 6, the String is explicitly cast with [method int]
var max_int = 9223372036854775807
print(max_int) # 9223372036854775807, OK
max_int += 1
print(max_int) # -9223372036854775808, we overflowed and wrapped around

Cast a [bool] value to an integer value, [code]int(true)[/code] will be equals to 1 and [code]int(false)[/code] will be equals to 0.

<description>
Cast a float value to an integer value, this method simply removes the number fractions, so for example [code]int(2.7)[/code] will be equals to 2, [code]int(.1)[/code] will be equals to 0 and [code]int(-2.7)[/code] will be equals to -2.

<description>
Cast a [String] value to an integer value, this method is an integer parser from a string, so calling this method with an invalid integer string will return 0, a valid string will be something like [code]'1.7'[/code]. This method will ignore all non-number characters, so calling [code]int('1e3')[/code] will return 13.
